The control of both bottom and distillate compositions is achieved by using conventional two point feedback control (WoodandBerry1) and non-interacting control (WoodandBerry2). Because of coupling, conventional control has a poorer performance when compared to the non interacting control system....

Two tanks in are disposed in series. The level of tank 2 must be controlled despite a sine wave disturbance in the flow F3. This is achieved by changing the flow rate F0 of liquid to tank 1. The tanks areas are A1 and A2. Flow equations depends on constants K1 and K2. A proportional control with...
